You are a lighthouse and day & night you vibrate and send energy to people around you no matter where they are on this planet they are. They can unconsciously feel this energy and then decide to react or now. Like a Phone call, for example, this situation happens to us several times per year.
What is she getting out from it? Remember that for them sex is more a hassle than fun. Some girls really love sex, but most are just using it to get something in life. She is giving you sex so she can get something back. What do you my friend give in return for sex?
You bring a girl home, everything is going smooth, you open a bottle of wine, play some music, you are enjoying the conversation with her, she loves it, you start kissing and then in one moment she says the killing sentence:
“Just for you to know, we not going to have sex tonight”
This is the difference that makes the difference. Use texting to build amazing connection, amazing conversation with a girl, get to know her, have fun with text, have a great time with her, get her used to send you photos, do everything you can do so she is dying and waiting for a moment to meet you in person. Remove the focus from trying to “close her” or meet her as soon as possible, to building best conversation you can. Get to know her, get her to open up to you, make her feel like she knows you and wants to know more about you. Then and only then she will very likely have free time to meet you.
